Current Garmin fitness mass storage products like the Edge, Forerunner, and vivoactive series, store your activities in the accessible file structure of the device. This provides a better user experience when using the device with a computer. There may be instances in which additional space is needed on the device. For example, the device memory may fill to the point a software update cannot be sent to during sync interactions with Connect Mobile, Garmin Express, or WiFi. In these circumstances, it becomes necessary to make additional space on the device.

If attempting to permanently delete activities from the device, you may need to delete the associated FIT file. Before deleting from the device, verify all activities have successfully uploaded to Garmin Connect.
